FREMONT - Children can design their own roller coasters, discover how airplanes fly, and experiment with algae during a new summer program at the Rutherford B. Hayes Presidential Library and Museums.

The Frohman Summer Series: HANDS-ON HISTORY offers three activities for children ages 6-11 using materials from the Charles E. Frohman Collection at the Hayes Presidential Library and Museums to gain firsthand knowledge in history through science, technology, engineering and math initiatives.

“HANDS-ON HISTORY weaves together our local history and science through interactive STEM projects that bring the past alive,” said Nan Card, curator of manuscripts.

The sessions are free. Kids can attend one or all. Parents are welcome to attend with their children. Each session is from 10 a.m. to noon.

The schedule is:

• June 20 - Aviation: Students can see the early aviators and the airplanes they constructed at Sandusky’s Battery Park. Students will discover the forces of flight and learn how early aviators applied them to their aircraft and the dangers they encountered.

• July 18 - Roller Coasters: Students can learn about speed, strength, gravity and other principles of physics and engineering by designing a roller coaster using a variety of materials. From 1892 to the present day, coasters have been a top attraction of Cedar Point amusement park generation after generation. Using the Frohman Collection photographs, drawings and documents, students will analyze and build models of roller coasters.

• Aug. 15 - Ever-Changing Lake Erie: Students will learn about lake activities such as ice harvesting and fishing. They then will compare firsthand Lake Erie’s present condition and its plant and aquatic life to that of the early 20th century. Using water brought from Lake Erie, students will learn about pollution, how to grow algae, and study its negative effects on the lake when its growth reaches dangerous levels.

Registration is required and limited to 10 kids per session. Register by calling Nan Card or Julie Mayle at 419-332-2081, ext. 239, or email them at ncard@rbhayes.org or jmayle@rbhayes.org.
